In 1997, Sri Lanka became a member of the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) which also includes Bhutan, India, Nepal, Thailand and Myanmar. BIMSTEC is looking into a free trade agreement with Japan to boost trade, which has been declining since 2000. By 2007, only 2.4% of Sri Lanka’s total exports were to Japan, mostly tea, rubber, fish and precious stones.
